Browser Inspection Surface

The browser integration turns the engine sandbox into an inspection surface. It keeps the live canvas, adds scene selection, zoom controls, wireframe toggling, scene-focus copy, and a collapsible runtime tree.

That tree is the important bridge between visual output and engine state. The moving scene can be inspected through the corresponding hierarchy, component labels, local/world transforms, anchors, rotations, scales, and node IDs.

• Demo scenes include stacked orbits, counter drift, layered motion, diagonal sweep arrays, in-place arrays, square paths, and star paths.
• The stage zooms from 0.1x to 2x.
• The tree supports local/world-space toggling per node.
• The browser route makes the runtime inspectable without opening the source.
